How to set up routing in Vue.js 2?

Question

Vue.js

"vue": "^2.6.10",
    "vue-router": "^3.0.3",

A blank page is now displayed in the browser.
The structure is simple - in the src/components folder there are 3 vue files (home, about, cars)
home.vue

        <h1>Home</h1>
    </div>
</template>

<script>
export default {
    name: 'home',
    data () {
        return {
            msg: 'Welcome to Your Vue.js App'
        }
    }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>

</style>
